Claims

[Scope of utility model registration request]

In an electrode for a vacuum interrupter in which a contact electrode is brazed to the end of a current-carrying shaft, a protruding part is formed on the outer circumferential surface of the contact electrode, and an auxiliary part having a substantially ring shape and a pressing part protruding inside. By providing a member and brazing the auxiliary member fitted with the contact electrode to the current-carrying shaft,
An electrode for a vacuum interrupter, characterized in that the contact electrode is fixed to the current-carrying shaft while the protruding part is pressed by the pressing part.
